Processes for producing ethylene and carbon monoxide mixtures from ethane |
(57) A method for producing a mixture of ethylene and carbon monoxide by contacting ethane
and an oxygen source at a temperature of at least 500°C to produce ethylene and carbon
monoxide. A method for producing an alkyl propionate by steps of: (a) contacting ethane
and an oxygen source at a temperature of at least 500°C to produce ethylene; (b) contacting
an alcohol, ethylene and carbon monoxide with an ethylene carbonylation catalyst to
produce the alkyl propionate; and (c) separating the alkyl propionate from byproducts
and starting materials. The method further comprises condensing the alkyl propionate
with formaldehyde to produce an alkyl methacrylate.
